Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting device for thin and flexible tapes such as magnetic tapes for storing computer information and tapes used in tape recorders.

When editing the above-mentioned tapes for internal use, the edited tapes are spliced together, but this connection requires that the edges of the tapes be firmly butted and glued together without overlapping or separating them. There is.

However, the tapes are thin and difficult to handle, and since the tapes are narrow, it is difficult to visually see the butt edges of the tapes, making it difficult to butt the tapes together.

Therefore, an object of the present invention is to provide a tape splicing device that can reliably butt the edges of tapes.

According to this invention, the tape is attracted to the tape guide groove by the air intake hole at the tape adhesion position, so it is possible to butt the tape along the guide groove without lifting the edge of the tape. Since the tape is illuminated from the bottom surface, the edges of the tape can be clearly seen, thereby eliminating separation and overlapping of the edges and ensuring abutment, resulting in good adhesion.

An embodiment of the present invention having such characteristics will be described in detail below with reference to the drawings.

The drawing shows a tape connecting device, and the top surface of the box body 1 has linear guide grooves 3 for guiding the tapes 2a and 2b.
is formed.

The adhesive position 4 at the center of the guide groove 3 described above is formed by a light transmitting body 5 such as a transparent plate or a semi-transparent plate that transmits light.
This light transmitting body 5 is provided with a plurality of small air intake holes 6.

Inside the box 1, an intake chamber 8 is formed by a partition wall 7 on the lower surface side of the guide groove 3, and a communication hole 9 is formed in the center of the partition wall 7. .

The above-mentioned intake chamber 8 is provided with a lamp 10 near the lower surface of the above-mentioned light transmitting body 5.

An exhaust chamber 12 is formed at the bottom of the intake chamber 8 by a partition wall 11.
A fan 13 is provided in the exhaust chamber 12, and a communication hole 9 between the center of the fan 13 and the upper partition wall 7 is formed.
The above-mentioned fan 13 is rotated by a motor 14 disposed at the lower part of the partition wall 11.

A plurality of exhaust holes 16 are formed in the circumferential wall 15 of the exhaust chamber 12 described above, and the exhaust air is exhausted through these exhaust holes 16 .

Note that 17 is a power supply, 18 is a power switch,
The aforementioned lamp 10 and motor 14 are connected to a power source 17 via the aforementioned power switch 18.

A pair of brackets 19 and 19 are arranged in series on one side of the box body 1 facing the guide groove 3.
．． 19 is connected to the arm 22.2 of the adhesive body 21 via the shaft 20.
2 is pivoted.

The above-mentioned adhesive body 21 is formed in a hollow shape and is provided so as to overlap with the above-mentioned guide groove 3 when it moves downward, and the smooth surface 23 that overlaps with this guide groove 3 has a small air intake hole 24.
Many holes have been drilled.

The adhesive body 21 described above is communicated with the intake chamber 8 of the box body 1 via a pipe 25.

When connecting the tapes 2a and 2b, first fit the tapes 2a and 2b into the guide groove 3 with their recording surfaces facing down so that their edges are located at the bonding position 4, and then turn on the power switch 18. Manipulate.

As a result, the lamp 10 is turned on to illuminate the bonding position 4 from below, and the fan 13 rotates to exhaust air from the intake chamber 8, thereby generating air in the intake hole 6 in the guide groove 3.

For this purpose, the tapes 2a and 2b are attached to the guide groove 3 at the bonding position 4.
This prevents the guide groove 3 from being attracted to the guide groove 3 and floating up from the guide groove 3.

As mentioned above, since the adhesive position 4 is illuminated from below by the lamp 10, this light beam is transmitted to the upper surface side by the light transmitting body 5, and the exposed positions and edges of the tapes 2a and 2b can be easily seen. can.

The tapes 2a and 2b in this state are moved along the guide groove 3 against the attraction force, and their edges are butted together without overlapping or separating.

This abutted state is maintained by adsorption force.

The adhesive tape for connecting the tapes 2a and 2b is a single-sided adhesive tape, and the non-adhesive side of the adhesive tape is adsorbed to the smooth surface 23 of the adhesive body 21 through the air intake hole 24, and then the adhesive body 21 is rotated. The edges of the tapes 2a and 2b are joined with adhesive tape by moving the tapes 2a and 2b to connect the tapes.

After that, by turning off the power switch 18,
The lamp 10 is turned off, the fan 13 is stopped, and the suction effect of the intake holes 6 and 24 is eliminated, so that the tape 2a
, 2b can be taken out from the guide groove 3.

Note that the intake hole 6 may be provided throughout the guide groove 3.
